Kelly Roberts, a Ph.D. candidate in family therapy and policy, has been studying marriage vows. She writes:
... they have pledged their faithfulness to “the supreme relationship status”... But I wonder, would vows be measured and stated any differently if the phrase, “to preserve, protect and defend” were to be included? ... Relationships do better when a couple can set boundaries and bottom lines against entities that threaten their substance. Relationships to better when there is safety provided and safety expressed among and between the two. And relationships do better when either person knows that loyalty exists, and their honor or heart or hopes and dreams will be defended by the other if threats become present from an outside source.
Relationships do better when their oath of office includes preserving, protecting and defending. And people can thrive and grow when they know their partner has their back.
